I'm glad that the rest of the exam described your husband as extremely healthy. I hope that he remains so for quite some time. That said, low cholesterol is increasingly being seen as a significant health risk. Google "low cholesterol health risks" and you'll see what I'm talking about. I almost didn't even post any of this because I prefer to focus on sharing positive news, but it may be useful to know what you're dealing with, at least in the eyes of the medical/insurance profession. Here's a quote from one of my favorite health sites to get you started:
"Just like our weight, there is an optimum with cholesterol as well. Some people believe that the lower your cholesterol, the healthier you are.
Nothing could be further from the truth. If your cholesterol is too low you will have an increased risk of mood disorders, depression, stroke, and violence. And these are only the KNOWN effects right now. There are likely many more currently unknown and unstudied [...]
Unfortunately, many people have low cholesterol who are not taking medications. I am one of them. This is largely due to my having beta thallasemia which is a genetic defect in the size of red blood cells that is also associated with a low cholesterol.
Yes, my risk for heart disease is quite low, but the risk for the other diseases mentioned above is clearly elevated.
It seems that low cholesterol in many individuals is related to a non optimized gall bladder and liver function."

Also:
Abnormally low levels of cholesterol may indicate the following:
• hyperthyroidism, or an overactive thyroid gland
• liver disease
• malabsorption, or inadequate absorption of nutrients from the intestines
• malnutrition
